Button input or inputing using IF.

I basically need to switch between ranges of cells to data input alot. so i thought of making a fixed field to enter the data which transfers the data over to designated cells .

Attached is an example.

I am not too sure which one will work, the If statement captures the data but when i switch out , the entry is gone .

Instead is it possible to use the button to record the data once?

I may sound confusing but please view the file for a better idea

p.s. i cant make a data input form reason being the large amount of cell ranges which may shift.
